An RCD or residual-current device is a leak detector and is for human safety.
It measures the amount of power going into and coming back from a circuit. If only a very small amount out, the RCD trips and saves the humans and property from further harm and risk.
A fuse or circuit breaker is a safety device that activates over the circuit load. This is much more than a small leak of electricity that would activate an RCD.
Depends on various factors: Mains from street; how many light and power outlets in each room; the size of the home; additional services such as home automation, security, TV, data, & phone. I am happy to quote off plans and/or talk about the project needs with you.
Since first established in 1927 in New Zealand, electrical regulations have been constantly changing with an emphasis on better electrical protection and safer electrical practices. The aim is to reduce the amount of fatalities, injury, and fire caused by electrical works.
When an Electrician changes a circuit, that circuit needs to comply with the regulations of the day. If your electrics are old, chances are they would not completely comply with today’s regulations. I can often give an indication over the phone or by email, if given the age of the building, existing alterations of significance, and desired electrical additions.
When you are resetting circuit breakers or changing fuses too often. When you turn on your air conditioner and the lights dim in the room. When your lights flicker or go on and off. When you can smell wiring burning. When you have six electronic devices going into one outlet in back of your electronics center. When you have receptacle outlets overburdened by multi-plug strips. When a three-prong plug needs a two-prong adapter. If you have to run extention cords to plug in electrical devices.
The reason that a circuit breaker trips is because it overloads or there is a short circuit. The power turns off.
I’ve purchased a property and the power has been shut off for more than a year. The electric company won’t switch it back on. What should I do?
Get in touch with an electrician or inspector to inspect the property’s wiring.
If any it matches any of the below, you should get in contact with us:
- If it looks damaged
- If it is tripping the circuit breaker
- If it’s not fixated on the wall properly
